Abstract
The aim of this study was to explain the Numb anti-cancer effects in the prostatic cancer. Collecting the 20 prostatic cancer patients and analyzing the correlation between Numb and Glease score. Transfection Numb into DU-145 and PC-3 cells, measuring the proliferation rate of difference groups by MTT assay, evaluating the cell apoptosis and cell cycle of difference group by Flow cytometry; measuring the invasion and migration abilities by transwell and wound healing assays. In the nude mice experiment, establish prostatic cancer nude mouse subcutaneous planting tumor model by DU-145 cells, Injection the Numb from tail vein. Evaluating the tumor volume and weight. The Numb protein expression was decreased with Glease score increasing. The proliferation rate of Numb groups were significantly decreased compared with NC groups (P<0.05, respectively). The apoptosis and G1 phase rates of Numb groups were significantly enhanced compared with NC groups (P<0.05, respectively). The invasion and migration abilities of Numb group cells were significantly weaken compared with NC groups (P<0.05, respectively). In the WB assay, The relative proteins (Numb, P53, Cyclin D1, Rac1, MMP-2 and MMP-9) expression were significantly differences betwe...Continue Reading
